Method and device for measuring and calculating burning loss rate of dry quenching coke

Abstract

The invention provides a method and device for measuring and calculating the burning loss rate of dry quenching coke. The method comprises the following steps: detecting the mass of red coke loaded into a dry quenching furnace within preset time and the mass of carbon in the red coke, and calculating the mass percent of the carbon in the red coke; detecting the volume of circulating gas diffused by the dry quenching furnace, the type of carbon compound gas in the circulating gas and the volume of the carbon compound gas in the circulating gas in the dry quenching process of the red coke, and calculating the volume percentage of the carbon compound gas in the circulating gas; and according to the type of the carbon compound gas in the circulating gas, calculating the burning loss rate of the coke from the mass of the red coke, the mass percent of the carbon in the red coke, the volume of the circulating gas and the volume percent of the carbon compound gas in the circulating gas by using a preset algorithm corresponding to the type of the carbon compound gas in the circulating gas. According to the method and the device for measuring and calculating the burning loss rate of the dryquenching coke can measure and calculate the burning loss rate of the coke in real time, improve the burning loss rate of the coke, and are of guiding significance to dry quenching production regulation and control.

Description

technical field [0001] The present invention relates to the technical field of CDQ, in particular to a method and device for measuring the burning loss rate of CDQ coke. Background technique [0002] Coke is an important raw material for industrial production. The advanced degree of its production technology and product quality directly affect the economic and technical indicators and production operations of industrial production. In recent years, under the advocacy of energy saving and environmental protection, the CDQ process has achieved unprecedented development. It refers to a coke quenching process that uses circulating gas to cool red coke. The CDQ process not only has the advantages of energy saving and environmental protection The wet coke quenching process is also superior to the wet coke quenching process in terms of improving coke quality. [0003] During the CDQ process, the red coke is loaded into the CDQ furnace, and the low-temperature circulating gas is tr...

Problems solved by technology

[0004] The existing coke loss rate is usually calculated by counting the amount of red coke loaded, discharged coke and coke powder output of the CDQ furnace within a period of time (such as one month, one year, etc.), and then calculating the discharge coke and coke powder output The ratio between the sum and the amount of red coke loaded is obtained. Although this method is simple, it cannot realize real-time on-line monitoring, which is not conducive to the effective command of production by operators and the reduction of coke burning loss. For the production operation of CDQ equipment Regulatory guidance is less meaningful
